I watched a couple of them game last season immediately he was appointed as head coach but they couldn't grab a trophy. So far they've impressed when I think they won't, at most the Europa League Competition.
They've not just had good performance there but also during the domestic league games.
He's top young coach, touring round the best clubs in Europe, now it's time to share his wisdom and knowledge of the game to other younger players in the game. For them to be this consistent, then they have done well, they've just had a single draw.
More challenging test would come up next month that would determine if they could go half of the season at the top completely. Winning the Europa League is something I doubt, there are some big clubs dropping out from the Champions League that would cause them lots of problems.
Bayern Leverkusen has been delivering rightly since Alonso took on the managerial mantle, the club has been scoring back to back with improvement in points and the team's performance. They now make the German League tough and they still stand out in most of their games, In the coming months, they'll have to face a fierce battle of striving to maintain their top spot because any derailment will cost them a chance to retain that position.
The Europa League contest currently and gradually would get tough for them to win but they still have a shot at it. Although a lot of teams are falling from the UCL down to Europa and Leverkusen needs to be fit enough to scale through them if they really want to lift the trophy, there's positivity no doubt but football is unpredictable and no team should be underestimated.
